Getting your product to market as quickly as possible is key to business success, but what if transporting your product carries significant potential health and safety risks? Such is the case for lithium-ion cells, batteries and battery assembly products.

A new whitepaper by CSA Group outlines new requirements for these products in the latest edition of the United Nation’s (UN) 38.3 – Transportation of Dangerous Goods, Manual of Tests and Criteria, and how CSA Group’s world-class energy storage testing program can help businesses mitigate risk and increase speed to market.

General requirements
UN 38.3 requirements include eight tests, with the first five needing to be performed in sequential order using the same samples:

1. Altitude simulation
2. Thermal test
3. Vibration
4. Shock
5. External short circuit
6. Impact/crush (primary and secondary cells only)
7. Overcharge (secondary batteries only)
8. Forced discharge (primary and secondary cells only)

What’s new?
The G level for shock peak testing of large batteries has been reduced, with shock pulse now based on constant energy rather than constant acceleration. For cells and batteries under 12 kg, testing starts at 150G/6ms, and allows for reduced peak above 4 kg. For cells and batteries over 12 kg, testing starts at 50G/11ms, and allows for reduced peak out to 120 kg.

In addition, short circuit test temperature conditions to allow for testing inside or outside of a temperature chamber or oven have now been clarified. Samples may be preconditioned and then tested at ambient temperatures.

For battery assemblies with capacities greater than 6,200 Watt-hour, testing or engineering demonstration requirements are added to address overcharge, short circuit and over-discharge between batteries within an assembly.

Have a trusted certification body (CB) at your side
Outside of UN 38.3 requirements, you will need to comply with country-specific standards, such as IEC 62133-1 and IEC 62133-2, which have been adopted by Canada, the U.S, and other countries. To access markets in multiple countries with a single common testing document and certificate, you should obtain a CB report to help reduce additional repeat testing and expense.
